How to change labels in approval notifications?

Summary:

Our goal is to change labels in Approvers area into an approval notification

Content (required):

Hi, we would like to change the labels "Approved by" and "Submitted by" into an approval notification.

The approvers area is generated by a sub-template called by the rtf of the notification, which is written like that:

<?template:FusionHistoryRegion?>

TSORA_BIP_TOKEN_HISTORY_REGION_BIP_TOKEN

<?end template?>

(ORA_BIP_TOKEN_HISTORY_REGION_BIP_TOKEN is not a variable)

Is it possible to edit those labels and how can we do it?

Thanks

Best regards, Giuseppe
